Abstract: In apparatus for gunnery practice by which firing towards a target comprising a reflector is simulated by laser emissions, a first radiation emission at firing is used for ranging, to ascertain a time interval following firing at which a round of a selected type of ammunition will arrive at the target. After that interval following firing, a second emission is used to obtain a fix on the target. The second emission comprises pulses encoding information about ammunition type and relation of point of impact of the simulated round to target location, to be decoded at the target and used for evaluating hit effect.

Abstract: An elongated vibration transmitting body, extending vertically in a tank, is coupled at its top to an exciter that recurrently imparts brief periods of vibration to the body. A similar vibration receiving body, in spaced, parallel relation to the transmitting body, is coupled at its tip to a vibration detector. Rigid horizontal members connected to both bodies and vertically spaced at uniform intervals serve as sonic bridges between them. Calculating means, connected with the exciter and the detector, determines level of liquid in the same tank on the basis of number of crosstalks through sonic bridges and time between crosstalk through lowest exposed sonic bridge and beginning of crosstalk through liquid.
